Looping if/else statement

I'm in a code challenge and it asks me to repeat the word "Yay!" as many times as was input by the user. I'm creating an if/else statement but can't figure out how to get it to loop if the total number of "Yays!" is less than the input. for example, I want something like:

if(total <= number) { Console.Write("Yay!"); total += 1; repeat; } else if(total == number) { break; }

Is there a command to do that? I can't find it on Google.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            var total = 0.0;

            bool keepGoing = true;
            while (keepGoing)
            {
                Console.Write("Enter the number of times to print \"Yay!\": ");
                var entry = Console.ReadLine();
                var number = int.Parse(entry);

              {
                Console.Write("Yay!");
                total += 1;
                if(total <= number)
                {
                 Console.Write("Yay!");
                 total += 1;
                  if(total <= number)
                {
                 Console.Write("Yay!");
                 total += 1;
                    if(total <= number)
                {
                 Console.Write("Yay!");
                 total += 1;
                      if(total == number)
                      {
                        break;
                      }
                }
                }
                }
              }
            }
        }
    }
}

You should use a loop to avoid repeating the same few code lines over and over. But the prompt and input and number conversion should not be inside the loop, they should each be done only one time.

Yes because right now you ask the user again and again after every new iteration through the loop.

So the way you can solve this is to get all the necessary data BEFORE you enter the while loop. In the while loop print "Yay!" for the number of times the user has put in. So you need some sort of loop count that you can set to 0 (an integer would be the best for this task (no need for a double)). Then you put the condition (when the while loop should stop) into the while loop:

while(condition here)
{

}

(Also don't forget to increment (adding + 1) to the loop count variable. Otherwise you will end up in an infinite loop. No need for this keepGoing bool and you also don't need that many if statements.

You can do this :)
